Re: 1980 CB650z RC03 Café Racer (ish) project

Just got the tank parts together and I'm so scared that I'll scratch the paint.Wet sanded the lock and cap in 3 stages to get them smooth then used a 3M pad to get the brushed look.

The emblem was horrible so I had to bead blast it and re-paint it.

I know this thread is older-ish.. but it'd be awesome if you could throw up some finished product pics. Really dig that powder color/paint combo

Got some time left this weekend to put together the last pieces.Had some problems with a leaking master cylinder but it's all fixed now. The aftermarket (chineese) mastercylinder was not cutting it. It was made for a dual disk setup but was way to soft. Had to use the original MC and modify the new lever to make it fit.I put a couple of shakedown miles on it, everything good so far.All that is left now are adjustments and small improvements... and recheck every nut and bolt...

I wasn't happy with my muffler so I had to do something about it.It's originally a Marshall 4-1 system. The muffler is too long for my taste and I needed it to be a bit less restrictive.I cut the muffler to the desired length, an inch behind the rear axle bolt, made a removable baffle using a small diameter exhaust pipe from a car and perforated it (yes manually in a drill press!!).I cut a ring that I welded into the opening. This ring has 5 threaded holes that the baffle attaches to with five M5 stainless allen bolts.For now I'm not packing the system. If needed I will use coarse steel wool (for muffler use).
